CARE AND MAINTENANCE
Notice
Do not use harsh abrasives or caustic cleansers to clean fixture surface. A mild detergent, warm water, and a
softcloth will remove normal dirt and soap accumulations from fittings and surfaces. Rinse thoroughly after
cleaning and polish with a soft dry cloth to restore original luster of material.
Do not use cleansers in tank. Products containing chlorine (calcium hypochlorite) can seriously damage
fittings in the tank. This damage can cause leakage and property damage. American Standard shall not
be responsible or liable for any tank fitting damage caused by the use of cleaners containing chlorine
(calcium hypochlorite).
